Diameter d = 2 r ⇒ r = d 2 . {\displaystyle d=2r\quad \Rightarrow \quad r={\frac {d}{2}}.}. For a convex shape in the plane, the diameter is defined to be the largest distance that can be formed between two opposite parallel lines tangent to its boundary, and the width is defined to be the smallest such distance.

Diameter The diameter of a circle is the distance from a point on the circle to a point radians away, and is the maximum distance from one point on a circle to another. The diameter of a sphere is the maximum distance between two antipodal points on the surface of the sphere. If is the radius of a circle or sphere, then . The ratio of the circumference of a circle or great circle of a sphere to the diameter is pi, SEE ALSO: Brocard Diameter, Circumference, Circumradius, Circumsphere, Generalized Diameter, Graph Diameter, Pi, Polygon Diameter, Radius, Sphere, Transfinite Diameter.

What is Diameter Breast Height? Definition of Diameter Breast Height. A tree's diameter at your breast or chest height is the most common tree measurement made on a tree by tree professionals. It is also called DBH for short. The only other measurement made of a tree as important is a tree's total and merchantable height. This diameter is measured over the outside bark using a diameter tape at the point forester's call breast height. Breast height is specifically defined as a point around the trunk at 4.5 feet (1.37 meters in metric using countries) above the forest floor on the uphill side of the tree.

Circumference of a Circle A circle is a shape with all points the same distance from its center. A circle is named by its center. Thus, the circle to the right is called circle A since its center is at point A. Some real world examples of a circle are a wheel, a dinner plate and (the surface of) a coin. The distance across a circle through the center is called the diameter. A real-world example of diameter is a 9-inch plate.

Circle A circle is the set of points in a plane that are equidistant from a given point . The distance from the center is called the radius, and the point is called the center. Twice the radius is known as the diameter . The angle a circle subtends from its center is a full angle, equal to or radians. A circle has the maximum possible area for a given perimeter, and the minimum possible perimeter for a given area.

- Circumference - Circumference of a circle. 1  The circumference of a circle is the distance around it. 2  The circumference of a circle relates to one of the most important mathematical constants in all of mathematics. 3  Or, equivalently, as the ratio of the circumference to twice the radius.

Circle The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle. And here is the really cool thing: When we divide the circumference by the diameter we get 3.141592654... which is the number π (Pi) So when the diameter is 1, the circumference is 3.141592654...

Circle The radius is the distance from the center of the circle to its edge. For example, if the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. 2. If you know the circumference of the circle, divide it by π to get the diameter. π is equal to approximately 3.14 but you should use your calculator to get the most accurate results. For example, if the circumference of the circle is 10 cm, then the diameter is 10 cm/π, or 3.18 cm. 3. If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter.

- A circle is a set of all points in a plane that are all an equal distance from a single point, the center. The distance from a circle's center to a point on the circle is called the radius of the circle. A radius is a line segment with one endpoint at the center of the circle and the other endpoint on the circle. For the circle below AD, DB, and DC are radii of a circle with center D. A line segment that crosses the circle by passing through the center of the circle is called the diameter. The diameter twice the length of the radius. In the circle above AC is the diameter of the circle. A chord is a segment that also has endpoints on the circle, but the line does not need to cross through the center. On the circle below BC and AC are chords. A diameter is a chord that passes through the center of the circle. A secant is a line that intersects with a circle at 2 different points.

Circumference of a Circle The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter. Thus, the diameter of a circle is twice as long as the radius.
